Problems with the high-voltage system and battery of a Peugeot Rifter Diesel 2020

Hello, I had a similar problem with my Peugeot Partner Diesel, built in 2018. I have little car knowledge, but I can tell you what happened. I had a part of the high-voltage system defective. They had to replace some parts, but luckily it was under warranty, so it didn't cost me anything. But before I can give you more details, I would need some information from you. Can you tell me which warning lights on your dashboard come on? That could be a big help. Hope that helps you a bit!

Hey, thanks for your quick reply! The warning lights for the engine control unit and the high-voltage system keep flashing. My Rifter already has 177044 km on the clock and was last serviced about three months ago. Perhaps this can help with the diagnosis?

Hey, thanks for the info! My Peugeot Partner had similar warning lights on. It's possible that the high voltage system fault message could indicate a problem with the starter motor, as the battery is struggling to start. With the high mileage and sometimes not being serviced regularly, your starter motor could be worn out. Not sure if that could explain the power loss.... it could be a separate issue. My advice would be to take it to the garage asap before the problem gets worse. At the garage they have special tools and can find out the exact cause of the fault. Hope this helps!

Great, thanks for your advice! I'll take my Rifter to the garage as soon as possible before it gets any worse. You've helped me a lot, thank you again. Hopefully they will find the cause of the power fluctuations at the workshop. Stay healthy and always have a good journey!
